In China, there are still many ethnic groups who worship cows as totems. Tibetans worship yaks as totems. According to Tibetan historical records, some ethnic groups in Tibet originated from the "ancient yak and Qiang". The ancient Qiang people were "yak species, and the more Qiang they were, the more they were"; Totem worship of Mangniu is also a belief of Mongolians. The History of Buryat in Mongolia written by Lombok also records the myth and legend about the Mongolian ancestor "Idugan mated with Emperor Mangniu when roaming Lake Baikal". As an ancestral totem, its cultural communication and folk influence are far-reaching. Nowadays, whether it is the well-preserved primitive rock paintings about yak theme in Tibetan areas, the cow head ornamentation carved on bronzes in the Yin and Shang Dynasties, or even the yak bronzes unearthed a few days ago, it can be traced back to the totem worship culture of ancient China people with cattle as their ancestors.
